As a (very good I would say) product manager once told me - the product vision and strategy depends very much on the ability to execute. The market doesn't stand still, and what you _can_ do defines very much what you _should_ do.

What I mean to say here is that not even product management is reduced to just "understand the domain" - so it kinda' feels that your entire prediction leans on overly-simplified assumptions.

pretty big logic leap you made there. I didn't say understanding the domain was the only requirement. But certainly not understanding it will cause you to fail.
